Since Rebecca Gray was diagnosed with a degenerative eye disease, everything in her life consists of numbers. Each day her world grows a little darker and each step becomes a little more dangerous. Following days of feeling like someone’s watching her, Bec awakes at home to the cries of her son in his nursery. When it’s clear he’s not going to settle, Bec goes to check on him. She reaches in. Picks him up. But he’s not her son. And no one believes her. In a world where seeing is believing, Bec must rely on her own conviction and a mother’s instinct to uncover the truth about what happened to her baby and bring him home for good.
